[Bug 1604313] Re: Ubuntu 16.04: system freezes instead of suspend after undocking

2017-05-06 Thread Dennis
@Julius Thor: Unfortunately I couldn't reproduce your workaround. Once I
undock my laptop in the closed state it does not resume anymore.
Currently I am running

Linux thinkpad 4.4.0-77-generic #98-Ubuntu SMP Wed Apr 26 08:34:02 UTC
2017 x86_64 x86_64 x86_64 GNU/Linux

The only "solution" seems to be upgrading to the hwe kernel as
brandon211 mentioned. According to Christopher M. Penalver we need to
perform the SRU Procedure if we want a fix for kernel 4.4.0
(https://wiki.ubuntu.com/StableReleaseUpdates#Procedure).

2017-05-05 Thread Julius Thor
This bug is still in 16.04.

I seem to be able to work around this issue by closing the display while
in the bug. Let the display orientation update so only the external
monitor(s) is turned on, then undock the computer and finally open the
display and close it again.

But undocking the computer with the display open and then trying to make
the computer sleep will always make it lockup so that the cursor is the
only thing that's responsive.

the bug has been fixed in a later version of the package.

This is a significant bug in Ubuntu. If a fix for the bug in previous

the SRU Procedure [1] to bring the need to a developer's attention.

2017-03-02 Thread Dennis
@brandon211: good to know that there is a workaround, however I think it
is not really a solution because the kernel you are currently running is
not the default one. I am also running Ubuntu 16.04.2 but with the
standard kernel 4.4.0-64-generic where this bug is still present.
Furthermore installing the hwe kernel is not for everyone the best
solution, especially for enterprises, so this bug should be fixed in the
non hwe kernel as well.

2017-02-28 Thread brandon211
As the person who originally filed this bug, I'd like to add a comment: The bug 
actually doesn't affect me anymore to the effect that when Ubuntu 16.04.2 came 
out I switched to the new hwe-stack. This means I am (by) now running kernel 
4.8.0-39-generic which does fine so far.
Anyway, it would be nice to find out what the original problem was/is so that 
it maybe can be avoided to have this in the future again.

I also notice that the display changes are not detected properly. When I
undock, there is no change in display orientation and I can still move
the mouse over to the other screen which is not there (missing limb,
still felt). When I run Displays ("unity-control-center display"), the
screen flickers and the displays get rearranged but are still detected
as if they are still connected.

Christofer, I'll create a new bug report as soon as I get clarification
regarding my previous question.

ubuntu-bug linux

Please feel free to subscribe me to it.

I have the same laptop and am experiencing the same bug. I have tried
upgrading to 4.8.0-30-generic but that does not fix the problem for me.
I did try and turn off all monitors except the laptop monitor before
undocking and that allowed me to put the laptop to sleep. I could not
wake it up, though.

Given the fix commit came after 4.4.0-28-generic, and either including

understand why a (reverse) bisecting between 4.7-rc7 and 4.8.1 is needed
because the problem is not present in both versions.

2016-10-14 Thread Christopher M. Penalver
brandon211, the next step is to fully reverse commit bisect from kernel
4.7-rc7 to 4.8.1 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this
following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Also, the kernel release names are irrelevant for the purposes of
bisecting.

It is most helpful that after the fix commit (not kernel version) has
been identified, you then mark this report Status Confirmed.

Thank you for your help.

This is somewhat different to my case, where a freeze comes from the "go to

[Bug 1604313] Re: Ubuntu 16.04: system freezes instead of suspend after undocking

2016-08-18 Thread Luke Murray
I am getting this problem on a Thinkpad x260. I have two displayport
monitors attached to the docking station. If the machine is booted
docked, undocking causes a freeze. if the machine is booted undocked,
docking causes a freeze.

Kernel is 4.4.8-040408-generic

Oh, I forgot to install the linux-image-extra-... packages. So here we go:
4.4.0-21-generic: no problem
4.4.0-22-generic: no problem
4.4.0-28-generic: problem exists
4.4.0-31-generic: problem exists

Regarding the "bios-outdated" tag: I did a BIOS update, it now is
BIOS Information
Vendor: LENOVO
Version: JBET60WW (1.24 )
Release Date: 05/25/2016

but the problem persists.

I can try that. If you could point out how I can install previous
kernels? Just installing various linux-image-4.4.0. didn't to the
trick as there seem to be drivers missing (sound, graphic accel., etc.).

brandon211, could you please advise which various kernels specifically
where this issue was not present?

This issue did not start after an upgrade. The system however was
upgraded from Ubuntu 15.10. Yes, there were various kernels where this
issue was not present.

I tested the kernel you suggest. It fixes this bug *somehow*, which
means that suspend now works but when docking/undocking, the screen
configuruation with the monitor connected to the docking station is not
updated automatically anymore. Moreover, I have to dock/undock several
times until my screen is recognized correctly concerning the selectable
resolutions. And even worse, the combination Fn+F7 (for presentation
screen modes) now does not work sporadically.

2016-07-19 Thread Joseph Salisbury
Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

There are already bug reports stating general suspend problems (without
involvement of a docking station),
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1589139 and
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302/, both
containing comments of people still affected.
